On Interval Valued Fuzzy Bi-interior Ideals in Semigroups

open access: yesEuropean Journal of Pure and Applied Mathematics, 2023
In this paper, we study the concept of an interval valued fuzzy bi-interior ideal. We investigate the properties of an interval valued fuzzy bi-interior ideal in semigroups. We characterize a regular semigroup in terms of an interval valued fuzzy bi-interior ideal.

A Diagrammatic Temperley-Lieb Categorification [PDF]

open access: yes, 2010
The monoidal category of Soergel bimodules categorifies the Hecke algebra of a finite Weyl group. In the case of the symmetric group, morphisms in this category can be drawn as graphs in the plane.

Rough bipolar fuzzy ideals in semigroups

open access: yesComplex & Intelligent Systems, 2023
Fuzzy set (FS) theory and rough sets (RSs) are constructed to accommodate the data uncertainty. In contrast, the bipolar FS (BFS) theory can tackle the uncertainty and the bipolarity of the data in different circumstances.

On pliability of del Pezzo fibrations and Cox rings [PDF]

open access: yes, 2014
We develop some concrete methods to build Sarkisov links, starting from Mori fibre spaces. This is done by studying low rank Cox rings and their properties. As part of this development, we give an algorithm to construct explicitly the coarse moduli space

Fixed points of the EM algorithm and nonnegative rank boundaries [PDF]

open access: yes, 2015
Mixtures of $r$ independent distributions for two discrete random variables can be represented by matrices of nonnegative rank $r$. Likelihood inference for the model of such joint distributions leads to problems in real algebraic geometry that are ...

Soft intersection almost bi-quasi-interior ideals of semigroups [PDF]

open access: yesJournal of Fuzzy Extension and Applications
Generalizing the ideals of an algebraic structure has shown to be both exciting and valuable to mathematicians. In this context, the concept of Bi-Quasi-Interior Ideal (BQI-ideal) was proposed as a generalization of interior ideal, quasi-ideal, bi-ideal,

A study on SS- π- regular fuzzy ideals of semi groups

open access: yesTikrit Journal of Pure Science, 2019
In this paper,  the notion of SS -π- regular fuzzy ideals of semi groups as a generalization of regular fuzzy  ideal has been introduced and some of their important related properties have been investigated.

A domain of spacetime intervals in general relativity [PDF]

open access: yes, 2004
Beginning from only a countable dense set of events and the causality relation, it is possible to reconstruct a globally hyperbolic spacetime in a purely order theoretic manner.

New Properties of Anti Fuzzy Ideals of Regular Semigroups

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2019
In this article, we study some properties of anti-fuzzy sub-semigroup, anti fuzzy left (right, two sided) ideal, anti fuzzy ideal, anti fuzzy generalized bi-ideal, anti fuzzy interior ideals and anti fuzzy two sided ideal of regular semigroup.

Fuzzy Bi-Interior Ideals of Semigroups

open access: yesAsia Pacific Journal of Mathematics, 2018
Summary: In this paper, we introduce the notion of a fuzzy bi-interior ideal of semigroup and we characterize the regular semigroup in terms of a fuzzy bi-interior ideal of a semigroup.
